User-selected tag data associated with each zone area is received and stored associatively with positioning data in accordance with a document identifier corresponding to the tangible document in a data storage. Image data of tangible documents is generated, with each tangible document having the predefined layout. Character data is extracted from image data of each document according to positioning data and stored associatively with tag data in an associated database.

Description

BACKGROUND OF THE INVENTION

The subject application is directed generally to extraction of character data from tangible documents. The system is particularly suitable for use in setting up a template to allow users to quickly scan selected areas from standardized forms and relay extracted information to a database used in conjunction with a document management system.
Businesses rely on a continuous stream of information relative to tracking and managing orders, products, operations, shipments, inventory, billing, purchasing, and the like. Traditionally, much of this information was captured in one or more standardized forms, which would be manually read and relevant information humanly extracted and tabulated for future use.
More recently, there is increasing use of electronic documents, which do not require substantial space for storage, and which are more readily and widely accessible. However, there are still many situations that rely on tangible documents for information.

SUMMARY OF THE INVENTION

In accordance with one embodiment of the subject application, there is provided a system and method for setting data extraction fields for scanner input. Electronic document image data is generated from an associated tangible document, the tangible document having a predefined layout associated therewith and a document image corresponding to the electronic document image data is generated on an associated display. At least one zone area is generated as a sub-portion disposed with the document image on the display and positioning data is received from an associated user, the positioning data being representative of a user-selected location of the at least one zone area relative to the electronic document image. User-selected tag data associated with each of the at least one zone areas is received and stored associatively with positioning data in accordance with a document identifier corresponding to the tangible document in a data storage. Image data corresponding to each of a plurality of tangible documents is generated, each of a plurality of tangible documents having the predefined layout associated therewith. Character data is extracted from image data corresponding to each of the plurality of tangible documents in accordance with stored positioning data and stored associatively with tag data corresponding thereto in an associated database.
Still other advantages, aspects and features of the subject application will become readily apparent to those skilled in the art from the following description wherein there is shown and described a preferred embodiment of the subject application, simply by way of illustration of one of the best modes best suited to carry out the subject application.

The skilled artisan will appreciate that the subject system 100 and components described above with respect to FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG. 5, FIG. 6, FIG. 7, FIG. 8, and FIG. 9 will be better understood in conjunction with the methodologies described hereinafter with respect to FIG. 10 and FIG. 11, as well as the example illustrations of FIGS. 12-16, discussed in greater detail below. Turning now to FIG. 10, there is shown a flowchart 1000 illustrating a method for setting data extraction fields for scanner input in accordance with one embodiment of the subject application. Beginning at step 1002, electronic document image data is generated from an associated tangible document. In accordance with a preferred embodiment of the subject application, the tangible document has an associated predefined layout. A document image is then generated on an associated display at step 1004, with the image corresponding to the electronic document image data.
At step 1006, at least one zone area is generated as a sub-portion disposed with the document image on the display. In accordance with one embodiment of the subject application, the at least one zone area is representative of a portion of a scanned tangible document that includes extractable data, including, for example and without limitation filled-in parts of a standard form, standard parts of a document (management system identification component), and the like. Positioning data is then received from an associated user at step 1008. According to one embodiment of the subject application, the positioning data represents a user-selected location of the zone area relative to the electronic document image. At step 1010, user-selected tag data associated with each zone area is received from the associated user. The tag data is then associatively stored at step 1012 with the positioning data in accordance with a document identifier of the tangible document in a data storage.
Image data is then generated at step 1014 corresponding to each of a plurality of tangible documents, with each of the tangible documents having the associated predefined layout. At step 1016, character data is extracted from the image data corresponding to each of the tangible documents according to stored positioning data. Thereafter, at step 1018, the character data extracted from each of the tangible documents is stored in association with tag data corresponding to the documents in an associated database.
Referring now to FIG. 11, there is shown a flowchart 1100 illustrating a method for setting data extraction fields for scanner input in accordance with one embodiment of the subject application. The methodology of FIG. 11 begins at step 1102, whereupon the document processing device 104 generates electronic document image data from a tangible document having an associated, predefined layout. Suitable means of generating such image data include, for example and without limitation, scanning operation, image capture operations, and the like. It will be appreciated by those skilled in the art that such a layout includes, for example and without limitation, an order form, a spreadsheet, a receipt, an invoice, a reporting form, or other such document. A document image is then generated via a thin client on the user interface 106, the display 116, the workstation 122, or the like at step 1104 corresponding to the image data generated at step 1102. That is, an associated user is presented with an image of the scanned tangible document via a thin client operative on the user interface 106, the display 116, or the workstation 122.
Positioning data of a user-selected location of a zone area relative to the document image displayed via the user interface 106, the display 116, or the workstation 122 is received from the user via cursor placement thereon. In accordance with one embodiment of the subject application, the zone area corresponds to a rectangular box or other such indicia on the display corresponding to a field on the document in which is contained data for collection into the document management system of the server 128. At step 1108, the zone area is generated on the user interface 106, the display 116, or workstation 122 as a sub-portion disposed on the displayed document image. FIG. 12 illustrates an example thin client display 1200 depicting a scanned tangible document 1202 for use in accordance with the methodology of FIG. 11. As shown in FIG. 12, the thin client display 1200 enables the user to select one or more areas for character data extraction, as explained in greater detail below. FIG. 13 depicts the positioning of a user-selected zone area 1302, e.g. a selected input field, on the thin client 1300. It will be appreciated by those skilled in the art that such positioning is capable of being accomplished via a mouse, touch pad, or other similar input device associated with the workstation 122, the kiosk 114, or the user interface 106.
User-selected tag data is then received from the user for association with each zone area at step 1110. According to one embodiment of the subject application, the tag data includes one or more tag identifiers, such as, for example and without limitation, a purchase order number, a serial number, a date, a cost, a time, a quantity, shipping information, an address, and a name. FIG. 14 depicts a thin client 1400 on which is selectable one or more suitable tags 1402 for association with the user-selected zone area 1404. A determination is then made at step 1112 whether another zone area has been selected by the associated user. That is, whether the associated user has selected another field, line, or other area on the scanned document from which data is to be collected. Upon a positive determination at step 1112, operations return to step 1106, whereupon positioning data corresponding to the additional zone area is received. FIG. 15 illustrates a thin client display 1500 via which a first zone area 1502 is displayed indicative of an area from which character data is to be extracted, and the additional zone area 1504 as selected by the user.
When it is determined at step 1112 that no additional zone areas are associated with the document image data, flow progresses to step 1114. At step 1114, the tag data is stored associatively with positioning data and a tangible document identifier in the data storage 130 as a template. It will be appreciated by those skilled in the art that the template is preferably generated in a device-independent language, e.g. eXtensible Markup Language (XML) or the like. In accordance with one embodiment of the subject application, the template is stored in a document management system hosted by the server 128, as will be understood by the skilled artisan.
A determination is then made at step 1116 whether another template is to be created. That is, whether or not the user elects to input another tangible document from which a template is to be created. Upon a positive determination at step 1116, operations return to step 1102, whereupon electronic document image data is generated from a new tangible document for the generation of the new template. Operations then proceed with respect to the new tangible document for the generation of the new template as set forth above in steps 1104 through 1114.
Upon a determination at step 1116 that no additional templates are to be created by the associated user, flow proceeds to step 1118, whereupon login data is received via the thin client of the user interface 106, the display 116, or workstation 122. It will be understood by those skilled in the art that the methodology of FIG. 11 is capable of terminating after step 1116 with respect to an administrative user, and that step 1118 through step 1132 are capable of being accomplished via interactions of an associated user, an administrative user, or the like. Following receipt of the login data, data corresponding to each stored document identifier is generated on the thin client according to the login data at step 1120. According to one embodiment of the subject application, the login data is received via the user interface 106 or kiosk 114 and communicated to the server 128, which correlates the login data with accessible or authorized templates (based upon document identifiers associated therewith). The server 128 then returns such identifiers to the thin client for display to the associated user.
Selection data is then received from the associated user at step 1122 corresponding to a selected identifier, i.e. a desired template. The template corresponding to the selected identifier is then retrieved from the document management system of the server 128 at step 1124 by the controller 108 or other suitable component associated with the document processing device 104. Image data is then generated of tangible documents having the predefined layout associated with the template by the document processing device 104 at step 1126. That is, the document processing device 104 performs a plurality of scans of tangible documents that have the same layout as that of the template, i.e. completed forms to the blank form (template). Character data is then extracted from the image data corresponding to each tangible document in accordance with the template layout at step 1128. The extracted character data is then stored with associated tag data in the database, i.e. the document management system of the server 128, at step 1130. A determination is then made at step 1132 whether a different tangible document, i.e. one that does not conform to the predefined layout of the template, has been scanned by the document processing device 104. Upon a positive determination, operations return to step 1120, whereupon the associated user is prompted to select a suitable template corresponding to the different document. In the event that a different tangible document has not been received, operations with respect to FIG. 11 terminate after step 1132.
The foregoing description of a preferred embodiment of the subject application has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the subject application to the precise form disclosed. Obvious modifications or variations are possible in light of the above teachings.
